Hi! Pls help!

The ration of the number of Donovan's stickers to the number of Hong Yi'S stickers is 10 : 3. After Donovan gave Hong Yi 1/5 of his stickers. Hong Yi had 30 stickers less than Donovan. How many stickers did Donovan give to Hong Yi?


Thanks

Hi there,

Following pls find my worked solution:

<before>

D : H
10 : 3

<process>

D gave (1/5) to H.

(1/5) × 10u --> 2u

<after>

D : H
8 : 5

Given H had 30 stickers less than D, we have ...

D - H = 30
8u - 5u --> 30
3u --> 30
1u --> 10

D gave H 2u of stickers,

2u --> 2 × 10 = 20

==============

Trust this helps.

Do let me know again if this is different from your Answerkey or if theres further clarification.

Cheers,
Edward
